this practices are materialized on the maintainers-tools OCA
project. And frankly, we are very happy with the tags we came up
with for now. These labels came from our day to day needs. I
understand you want to do good. What we need right now is reviews on
the "needs review" tagged PR, help on the "help wanted" PR, fixes on
the "bug" tagged issues.

If you want to suggest changes in our tagging, please start by using
the existing tags, to get a real feel of how things are done. Then,
after a while, you may submit an Issue to open discussion.
